## What is Speed of Sound?

Calculates the speed of sound based on the local ambient weather conditions.

• Temperature (°C, °F)
• Pressure (kPa, mbar, psi)
• Relative humidity (%)

Speed units can be changed from meters per second or feet per second. Calculation is done using the method according to Cramer (1993). 

The app uses your location to obtain a local weather forecast and then makes the calculation. Your position is only obtained when refreshing the forecast and is not continuously monitored. 

Use the 'pull-to-refresh' gesture to update the calculation.
